I want to push elements to 2D array,

My code is,

        var results = [];
        var resultstemp = [];
        function bindlinks(aamt,id1) {
        resultstemp=results;        
            imagesArray.push($("#image1").mapster("get"));

            if(results.length==0)
            {
            results.push([id1]);    
            }
            else
            {
               var ck=0;
               var lng=results.length;
                for (var i = 0; i < lng; i++) {

                  if(results[i]==id1)
                  {

                    ck=1;
                     results = jQuery.grep(results, function(value) {
                        return value != id1;
                      });

                  }                                     
                }                   
                if(ck==0)
                {
                results.push(id1);                  
                }                   
            }

I want to push id as well as aamt to array. Here i am pushing only id to array. I am not sure about how to add aamt to second position in 2D array.

Help me please,

Thank you

I'm somewhat confused as to what you want to do... Can you reword the question? — HellaMad, Aug 24 '12 at 05:00
Can you please explain your end goal instead of just asking to fix the code? — Hazem Salama, Aug 24 '12 at 05:03
@DC_ In my code i am using 1D array and pushing id1. But i actually want to push both id1 as well as aamt. For that i need 2D array.. 1st position i want to save id1 and aamt in 2nd position — Erma Isabel, Aug 24 '12 at 05:05
@esimov yes, i want to push both id1 and aamt evenly to 2D array — Erma Isabel, Aug 24 '12 at 05:07

Change the declaration as follows:

var results = new Array();

and change the push as follows:

results.push([id1,aamt]);

Hope it would help

This isnt working since push takes only one element. When i tried this code the values id1 and aamt is pushed to same position in 1D array separated by comma – Erma Isabel Aug 24 '12 at 05:58
That is how a 2D array will look like. :) Eg: `[[1,2],[3,4],[5,6]]` – Xmindz Aug 25 '12 at 09:10

The logic behind the method to push two separate values in the same array evenly is something like this:

var array = [];
function push(id1, aamt) {
    for (var i= 0; i < 10; i++) {
        if (i%2 == 0) {
            array.push(id1);
        }
        else {
            array.push(aamt);
        }
    }    
}

push(10, 12);
console.log(array); // 10, 12, 10, 12.....

Take note i abstracted the code quite a bit, because for me was not too obvious what the code should have to do, but the principle is simple: use the modulo (%) operator to test if the value is odd or even. If odd add the first value if even add the second value.

Hope it helps.
